WEATHER-STRIP.

Specification of Letters Patent.

Patented Dec. 25, 1906.

To (all whom, it Uta/Z] concern:

Be it known that I, FRANK N UNNING, Jr., a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Weather-Strips, ofwhich the following is a specification.

My invention relates to means for preventing rattle and making aweather-tight joint in windows.

The object of my invention is to provide a simple, durable, andeffective device of the above character which maybe readily applied andwhich will present a neat and linished appearance, requiring no furtherattention to maintain its efficiency.

My invention consists of a strip of resilient material, preferably ofspring-brass or other non-corrosive 1naterialsucl1 as zinc, galvanizediron, or alu1niniumfolded longitudinally and having each of the foldsthus formed slightly bent backward longitudinally, whereby a doublespring is formed.

Myinvention also consists in the further details and in the improvedmode of application, as will be more fully pointed out and claimedherein.

In the drawings which serve to illustrate my invention, Figure l is asectional perspective view of a windowframe and sash in which the sashis provided with my improved weather-strip. Fig. 2 is a plan view of myinvention before it is applied to the sash, serving to illustrate themethod of folding and bending the strip longitudinally in order to formthe double spring above mentioned. Fig. 3 is a perspective view of aportion of my invention. Fig. 4 is a cross-section through thewindow-frame, sash, and my improved weather-strip, which has been applied to the sash.

The preferred construction of my invention is as follows: A strip of thematerial is folded longitudinally at 1 to form the two spring members 2and 3. The spring member 2 is bent backward longitudinally at a point 4near the fold l and the spring member 3 is to a less degree bentbackward at a point 5 near the free edge of the member. The two springmembers between the points 1 and 4 are substantially parallel, as isseen at 6, and I prefer to form openings, as at 7, through the parallelportions of the spring members, through which a suitable fastening,

either a screw or a nail, as is shown at 8 in Fig. 4, may be insertedinto the stile 9 of the sash to which my improved weather-strip isapplied. This fastening is driven firmly against the outer member of thestrip. The fastening being applied near the fold 1 and through theparallel portions of the spring members, while it holds the strip firmlyupon the sash, does not interfere with the proper action of the springmembers and is at the same time out of the way of the stop-bead 10,between which and the stile 9 of the sash the spring members 2 and 3 arecompressed in degree inversely proportional to the amount of space thathappens to exist between said stop and said sash in the particularwindow to which the weather-strip is applied and by their reaction exerta pressure which tends to hold the sash outward against the parting bead11, thus avoiding any useless play of the sash within the window-frameand preventing the annoying rattle of the window by the action of thewind against it or any other disturbing cause. Since the spring member 3is longitudinally parallel with the stopbead and forms a close bearingof considerable extent therewith at all times, as may be seen at 12 inFig. 4 of the drawings, my improved weather-strip serves the furtherpurpose of making a weather-tight joint when applied as hereindescribed. The spring member is bent backward at 5 in order to removethe hearing-point between the spring member and the stop-bead 10 fromthe edge of the spring member, and thus provide a properbearing-surface, as indicated at 12.

The raising and lowering of the sash has no effect upon the properworking of the spring members and the wcather-strip will be found not tovary in its effectiveness regardless of the frequency of the opening andclosing of the window.

\Vhile my improved weather-strip will be found to completely close allcracks or openings, it necessitates absolutely no constructive change inthe sash or their frames and no special form of pulley or othermodification of the fittings of the window and does not cover up thepocket or in any way interfere with the sash-balance. It will also befound to add largely to the finished appearance of the window, owing toits simplicity of construction.

\Vhile I have shown and described my improved weather-strip as being aplied to the lower sash of the window, it shou d be understood that it isequally applicable to the u per sash and would be applied in precise ythe same manner, the action of the spring members taking place betweenthe upper sash and the parting-bead 11, forcing the upper sash outwardagainst the outer bead 13, and any statement made in connection with theabove description of its application I to the lower sash would alsoapply to a description of its use upon the upper sash.

I claim- 1. In a weather-strip, a strip of resilient material foldedlongitudinally to form two.

spring members being bent backward at a point near the fold thus formedwhereby said spring members are maintained substantially parallelbetween said fold and said point'and means for attaching said stripwithin said parallel portion.

3. A strip of resilient material folded longitudinally and secured inoperative position near its folded edge and having two free edges eachadapted to exert pressure laterally from the other to engage awindow-frame and sash respectively.

4. In a weather-strip a strip of resilient material foldedlongitudinally upon itself whereby two spring members are formed, andada ted to exert ressure laterally from each ot er against t ewindow-frame and sash respectively between which they are adapted to fitand be moved, one of said spring members being bent backward at a pointnear the fold thus formed whereby said members are maintainedsubstantially paral lel between said fold and said point, and the otherone of said spring members being bent backward at a point near its freeedge as and for the purpose herein specified.
